Since yesterday I have been having a great problem with my Intel(R) Graphics 4600. It wouldn't let me open Nvidia control panel but I solved that problem by firstly uninstalling my Nvidia graphics driver with DDU and then Intel. Right now I am using Microsoft's driver (i guess, it is the one shown instead of Intel's driver at Device Manager panel) alongside Nvidia's. I tried downloading both Intel's latest and an older version but they both get stuck at setup process. It stops the set up when it tries to install Graphics driver. I am using Windows10 and GTX960M. I have a special manufacturer. (At the attachment you will see a photo of Device manager before I uninstalled Intel driver.) I am open to any solutions.

Besides trying the suggestion above, also remember that when you use an external graphics card the onboard Intel® graphics get disable automatically, in this case then to install the proper drivers we need to get them from NVIDIA’s web site:
